Three Kingdoms: I Rely on Technology to Defeat Power Schemes

[Exquisite Three Kingdoms, read with confidence] I, the "ancient mechanical restorer" of the National Museum, accidentally traveled through time and became Mo Huaiqiu, the last descendant of the Mohist family in the Warring States Period. On the eve of the Battle of Guandu, Yuan's army's food road collapsed, and a hundred thousand troops were crying for food. Others offered suggestions for a surprise attack, so I took out the blueprint: "Paddle-wheel ferry, sailing against the current, transports three thousand stones per day." The fire in Wuchao was soaring into the sky, and Chunyu Qiong was lying drunk in the tent. I set up an improved ladder: "Here are the blueprints of the fireproof granary. Who wants to live?" Cao Cao stared at the repeating crossbow I made: "Would you like this divine thing to be mine?" Zhuge Liang looked at the grain cart on my track: "Mr. Mo, can the difficulty of the Shu road be solved?" Everyone in the world says that power can rule the world, but I want to use gears to turn the troubled world! From the abandoned son of Yuan Ying to the famous man of Cao Ying, it is time for these three countries to change their way of life—— "Give me enough iron and I can move the entire era!"
